The technical evaluation should document any agreements on tasks or costs as a result of fact-finding. Finally, the technical evaluation should conclude with recommendations and direct traceability to the task sheets. PREPARATION FOR WRITING A TECHNICAL EVALUATION The basis for understanding and producing a cohesive technical evaluation is: (a Author: Robert Graham. The original motor sourcebook was prepared by technical staff at LBNL and the Resource Dynamics Corporation (RDC). The update Efficiency Opportunity No. 5: Using Variable Frequency Drives Efficiency Opportunity No. 7: Using the Service Center Evaluation Guide.. 45 SECTION 3: MOTOR File Size: 1MB. 5 2 FUNDAMENTALS Principle of Operation A large percentage of AC motors are induction motors. This implies that there is no current supplied to the rotating coils (rotor windings). Attachment C Technical Evaluation Criteria ED-NAGR (b) Timeliness of Performance – meets milestones and deadlines – quick turnaround time on requests – promptly communicates issues– reliable – stays on schedule – responsive to technical direction – completes tasks on time.

Operating Environment If this motor operates in severe environmental conditions, it will be indicated on the accompanying motor repair form. No repair methods or materials may be used which make the motor more vulnerable to these conditions than it was as originally built. If . Clause Friction and windage losses, iron loss describes testing the motor under no-load conditions. The no-load test follows the load-test immediately, with the motor at essentially the same temperature as at the end of the load test. Facilities must be available for decoupling the motor from the loading system in seconds.   The measurements shall be carried out with an instrument conforming to ISO ( Hz frequency range). With the motor at normal operating temperature, the vibration velocity shall not exceed mm/s RMS, or 4 mm/s PEAK, in any direction.. For bearings fitted with proximity probes, the unfiltered peak-to-peak value of vibration (including shaft ‘run-out‘) at any load between no load. The Technical Evaluation Motor No. 7 (TEM-7) test was a full-scale, full duration static test firing of a high performance motor-configuration solid rocket motor with nozzle vectoring. The final test report documents the procedures, performance, and results of the static test firing of TEM

  With other goods, the technical evaluation may be more intense. This is particularly true if the item in question is necessary for the protection of human life. A crash system in a vehicle will be extensively tested to ensure that the safety bags deploy and inflate at a rate that does provide cushioning for the occupants of the vehicle. In like. 10 Direct torque control | Technical guide No. 1 A DC machine is able to produce a torque that is: – Direct - the motor torque is proportional to the armture current: the torque can thus be controlled directly and accurately. – Rapid - torque control is fast; the drive system can have a very high dynamic speed response. Torque can be. in a motor are operated above the thermal capacity of the design, the insulation system in the motor can break down, causing it to “burn up.” Figure 5: Continuous Duty vs. Intermittent Duty –the longer the “off time” the more short-term horsepower can be delivered from the motor. 8 Motion control | Technical guide No. 9 Introduction Decentralized or centralized control In a system with centralized control, one unit contains all the .
